cellular

hematopoietic system
• twice as large as wild-type
• marked erythroid hyperplasia
• mild anemia
• reticulocytosis with an increase in red cell distribution width (RDW), reflecting the size variation
• Heinz bodies, reflecting precipitated hemoglobin are present
• young red blood cells, with erythrocyte shape irregularities and occasional inclusions

homeostasis/metabolism
• reduced catalase activity in erythrocytes
• in a methylcellulose colony assay the formation of burst-forming unit erythroid (BFU-e)-type colonies from mutant bone marrow progenitors is inhibited selectively by buthionine sulfoximine (BSO), a pro-oxidant that depletes cells of glutathione
• exhibit a more rapid and profound decreases in hematocrit levels and subsequent delayed recovery in response to phenylhydrazine,(PHZ), an oxidant that induces denaturation of hemoglobin, resulting in rapid erythrocyte destruction

immune system
• twice as large as wild-type
• marked erythroid hyperplasia

growth/size/body
• twice as large as wild-type
• marked erythroid hyperplasia
